"He's making a list
And checking it twice
Gonna find out Who's naughty and nice..."

It’s a simple warning from Santa Claus, really, and one that is easily understood. If you are good and on your best behavior throughout the year, you are in turn rewarded, with a stocking full of goodies and gifts under the tree. Conversely, if you are one of the “bad kids,” it might be a lump of coal that awaits you come Christmas morning.

While ultimately the decision comes down to Santa’s list (and only after he checks it twice, of course), we thought he could use a helping hand this year, and so we determined 2008’s Ten Naughtiest People in Sports.

While it seems most can follow the simple caveat from Father Christmas, unfortunately, that simple childhood forewarning is sometimes lost on those in the world of sport. With all the money and egos involved, sports has more than its fair share of naughty nominees. From self-centered and whiny athletes, to a infamous and boorish agent, to out-and-out criminals, the playing fields and front offices are full of people who should be expecting that big lump of coal come Christmas morning.
